Hunter's comment

Scientifically advanced professional neck trainer for rehabilitation, health and fitness and injury prevention.
Stand upright with your core engaged put the Iron Neck on like a hat. Tie it onto a weight cable and slowly turn your neck, feel the tensions melt away and the strength gathering.
